    Default How to Xray a Volcano

    http://dvice.com/archives/2012/01/cosmic-ray-muon.php

    In order to predict when a volcano is going to erupt, and how bad that eruption is going to be, it's helpful to have a picture of what's going on deep down inside the thing. Seeing as we don't have any volcano-sized x-ray tables lying around, scientists have simply started using the entire universe, and the cosmic rays that it produces, as an imaging system.

    It sounds like they're using muons (which are leptons), not x-rays/photons (which are bosons).
    "We grow up thinking that beliefs are something to be proud of, but they're really nothing but opinions one refuses to reconsider. Beliefs are easy. The stronger your beliefs are, the less open you are to growth and wisdom, because "strength of belief" is only the intensity with which you resist questioning yourself. As soon as you are proud of a belief, as soon as you think it adds something to who you are, then you've made it a part of your ego."

    Yes, the article says they are muons. But there is no other name for this procedure.

    What's a photon scanner? You mentioned x-rays/photons.
